MACHINE FOR FORMING FUEL-BRICKS.

SPECIFICATION forming part of Letters Patent No. 474,412, dated May 10,1892.

Application filed January 6, 1892.

To all whom it may concern.-

Be it knownthat I, J OHANN PETER SCHMIDT, a citizen of the UnitedStates, and a resident of Jersey City, in the county of Hudson and Stateof New Jersey, have invented certain new and useful Improvements inMachines for Forming Fuel-Bricks, of which the following is aspecification.

My invention has reference to improvements in machines for formingfuel-bricks of such a construction by which the mass of which the bricksare formed is mixed, pressed, and cut into bricks of the desired shape.

The construction of my improved machine is illustrated in theaccompanying drawings, in which V Figure 1 is a side elevation, partlyin section, of my improved machine for forming fuel-bricks; and Fig. 2is a vertical section on line x 00, Fig. 1.

Similar letters of reference indicate corresponding parts.

A A in the drawings represent the side standards of my machine,which areconnected with each other by cross-pieces a a and have elevated frameportions A A in about the middle of the side standards.

13 is a feed table or plate between the side standards and firmlyattached to the same, which table is provided with side boards I) Z),lined with smooth metal or glass strips 1) b. To the ends of the framerollers O C are attached and fitted in bearings, one of which is madeadjustable by an adjusting-screw 0'. Over the rollers G 0 runs a rubberbelt D, that covers the whole width of the table. The rubber belt can betightened or loosened by means of the said adj usting-screw of one ofthe bearings of the rollers G O.

Guide-rollers E E are fitted in bearings e 6, attached to. the middleportions of the side standards underneath the elevated frame portions AA, which bearings are provided with springs e 6', so as to impart to therollers a certain spring action. The aforesaid rubber belt is guidedbetween the said rollers, the

spring action of the rollers causing an even guidance of the belt.

To the shaft of the upper roller E the motive power is transmitted fromthe engine. This may be done by any suitable arrangement, and istherefore not shown in the draw- Serial No. 417,207. (No model.)

ings. The other end of the shaft of the upper roller E, as well as thecorresponding end of the shaft of the lower roller E, projecting beyondthe side standards, are provided with gear-Wheels 6 6 which mesh witheach other, so that the lower roller is rotated simultaneously with theupper roller. rollers and the gear-wheels respectively are of the samediameter. The gear-wheels are shown in Fig. 2.

In bearings f, attached to the elevated portions A A of the frame, runsa guide-roller F, and a second guide-rollerF is located over the formerand is secured to the frame by means of adjusting-screws F F, verticallyattached to the elevated portions of the side standards. The ends of theshafts of the rollers F F which project beyond the frame are alsoprovided with gear-wheels f f, Fig. 2, which gear-wheels, as well as therollers, are of the same diameter, so that by means of the gear-wheels asimultaneous rotation of the rollersF F is obtained.

At both sides of the elevated portions of the frame standards g and hareplaced upon the main side standards, which serve as bearings for theguide-roller G and H. Oiel' the said guide-rollers G and H runs a beltof rubber or any other suitable material, which is guided over the lowerroller F, as shown in Fig. 2. This belt is also of the same width asthat of the table B. In the upper portions 9 of the standards 9 abrush-roller G is fitted,

Of course the which receives its rotary motion from the roller G by abelt connecting the pulley g of the roller G with the pulley g of thebrushroller G, Fig. 2.

The standards It have laterally-extending arms h, which serve asbearings for a rotating shaft K of a square cross-section, which is solocated that its longitudinal edges are about in line with the upperedges of the side boards I) b of the table B. The shaft 1K receives itsrotary motion by a belt leading from the pulley 7c of the upper rollerE, Fig. 2, to a pulley of the said shaft, which latter pulley is notshown in the drawings. Instead of the arms h separate standards orbrackets for the shaft K may be used, which are mounted directly uponthe main side standards A A and serve as bearings for the said shaft.

Near the opposite end of the machine ICO standards 1 are mounted uponthe main side standards A A,into which a roller M is fitted, that isprovided with longitudinal radiating knife-blades m, which reach uponthe belt D when the said roller is rotated. The standards Z Z havelaterally-extending arms Z Z, which serve as bearings for the shaft L,having a number of cutter-disks Z firmly attached thereto. The edges ofthese cutterdisks reach also to the belt D. The shaft L receives itsrotary motion from the kniferoller M by means of a belt running over apulley of the said roller M, which pulley is not shown in the drawings,and over the pulley Z of the shaft L. Fig. 2. Rotary motion to theknife-disk M is imparted from the lower rollerE by a belt that connectsthe pulley n of the said roller with a pulley of the knife-roller, whichlatter pulley is omitted in I tate the carrying on of the same.

the drawings.

All the rollers of the machine are of the same lengthswhich correspondwith the width of the belt D and the table.

The machine is set in motion in the following manner: From the enginerotary motion is transmitted to the upper rollers E and from there tothe lower roller E. From the lower roller E belts are running to one ofthe rollers O and to the knife-roller M and set the said rollers inrotation. The second roller 0 is rotated by the rubber belt D. From theupper roller E the edged shaft K and the lower roller Fare rotated bybelt connections, and the upper roller F is put into a rotating motionby the gear connection with the lower roller F. The rollers G and H arerotated by the belt running over the said rollers and the lower rollerF, and the shaft L, bearing the cutter-disks, and the brush-roller Greceive their motion from the knife-roller M and the roller G,respectively, as described before.

My machine works in the followingmanner: Upon the belt D plates oareplaced and then the mixture of coal-dust, (KEG, with a binding medium,of which the fuel-bricks are to be formed,is laid upon the said platesbefore the edged shaft K. The machine is then setinto motion and themixture fed to the edged shaft K, which more thoroughly mixes the massand distributes the same over the plate 0. The mass is then fed by thebelt D and the plates 0 below the belt 2' and pressed by the sametogether to a certain degree of density, and from there to thecutter-disks Ziwhich cut the same info longitudinal bars. As soon as thebars come into contact with the longitudinal knives of the rotatingroller M they are cut into bricks. The plates with the bricks thusproduced are then removed from the belt D at the other end of themachine, and the bricks are then dried in an oven.

The machine works continuously and the mass is carried after upon thebelt D before the edged shaft K in the proportion as the bricks leavethe machine at the other end of the same.

The brush-roller G serves to keep the belt 2' always clean when themachine is working.

The metal or glass strips by which the side boards of the table arelined serve to keep the edges of the mass smooth and to facili- Thecutter-disks Z and the knives m may be changed, so that bricks of anydesired shape may be formed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a machine for forming fuelbricks, a rotatingshaft of a square cross-section to more thoroughly mix the fuel mass anddistribute the same over the feed-belt, substantially as set forth.

2. In a machine for forming fuel-bricks, the combination of the rollersF F with the rollers G and II and the belt 2', running over the lowerroller F, and the rollers G and H, by which belt the fuel mass ispressed to gether when the same is fed over the table, substantially asset forth.

3. In a machine for forming fuel-bricks, the combination of thespring-acted rollers E E, one located over the other one,with the endrollers O C and the belt D, guided over the said rollers O O and betweenthe spring-acted rollers E E, substantially as set forth.

Signed at New York, in the county of New York and State of New York,this 12th day of December, A. D. 1891.
